This VBA code will loop though all the text files in a directory that user picks from an application box and print a list of them. This code can be modified to be used in many scenarios for any file type.

 

Sub LoopThroughAllTextFilesInFolder()

    'Declarations
        Dim wb As Workbook
        Dim DirPath As String
        Dim FileName As String
        Dim FileExt As String
        Dim UserFolderChoice As FileDialog
        Dim i As Integer
        Dim howmany As Integer
    'Declarations End

    'Regular Stuff
        Application.ScreenUpdating = False
        Application.EnableEvents = False
        Application.Calculation = xlCalculationManual
    'Regular Stuff End

    'User's Folder Choice
        Set UserFolderChoice = Application.FileDialog(msoFileDialogFolderPicker)

        With UserFolderChoice
          .Title = "Select A Target Folder"
          .AllowMultiSelect = False
            If .Show <> -1 Then GoTo AllGood
            DirPath = .SelectedItems(1) & "\"
        End With
    'User's Folder Choice End

AllGood:

    'Check if path is empty
      If DirPath = "" Then GoTo JumpToEnd

    'File Extension
      FileExt = "*.txt"

    'Let's find the first file & how many total files we have
      FileName = Dir(DirPath & FileExt)
      howmany = Len(Dir(DirPath & FileExt))

        'let's loop though them
            For i = 1 To howmany

                'print the name of the file
                Debug.Print FileName

                'move to the next file
                FileName = Dir
            Next i

'Done!!!

JumpToEnd:

    'Regular Stuff
        Application.EnableEvents = True
        Application.Calculation = xlCalculationAutomatic
        Application.ScreenUpdating = True
    'Regular Stuff End

End Sub
